- Rigidity: Ensure minimal tool overhang and rigid workholding to prevent chatter and vibration
- Entry Method: Use ramp or helical entry; avoid direct plunging into solid material
- Speed/Feed Adjustment: Reduce cutting speed by 20% for interrupted cuts or uneven surfaces
- Tool Inspection: Check cutting edges for wear before each operation; replace when flank wear exceeds 0.3 mm
- Storage: Store in original packaging away from moisture and corrosive environments
